In movies and literature, being a vampire is a permanent condition. They are Undead and the only other option is dead. I am unaware of any movie or book which reversed this condition to normal life.
And for the same reason many of us are fascinated by serial killers vampires are attractive in an horrific way. They are not infrequently even protagonists, as in the Twilight and Underworld (I think it was: vampires versus werewolves) series.
I was reading a quote from Jack London the other day about how ALIVE the wolves in a wolf pack feel in a hunt. They have a blood lust and all their senses are alive. Most hunters will describe something similar.
Vampirism, to me, is unprocessed gut energy, both in the literal physiological sense of latent tension in everything touching the unmyelinated vagus nerve, and in a subtle energetic sense. The two are obviously connected.
This is true of both werewolves and vampires. And both exist in the night, which is to say our deep unconscious, in our Shadow.
Vampires feel continual mild hunger, whereas werewolves feel periodic intense rage and hunger.
Both of these are emotional conditions in which trauma overlays primitive biological urges. I certainly would disagree in most respects, but it has been said that our bodies and brains exist as chassis’s and protective matrixes in service of our bellies—survival—and our sex—our reproduction.
Vampirism and Werewolfism are thus natural to us. They are the substrates upon which we are built.
Here is my point: psychically all unconscious myths can be entered in dreams and meditation, and perhaps drug induced altered states, and RELEASED.
It is a curse to feel emotionally hungry all the time. There is no other way to put it. The solution to vampirism is communion, is a deep and fulfilling emotional connection to others. This sates that hunger, and the Undead become alive again.
It seems to be the case that there are no permanent fates in this universe that we do not choose perenially.
